Transpiration works because water sticks to itself - it is cohesive and is transported up through the xylem vesselst

The cohesion theory is a theory of inter molecular attraction that explains the processes of water flow upwards (against the force of gravity) through the xylem of plants... water is constantly lost through transpiration from the leaf

The effect of wind on transpiration

Water diffuses into the plant at the roots by osmosis

Excess water evaporates from the stomata

As water is lost from the leaves, more water is pulled up from the roots...

...Because water sticks to itself (it is cohesive)

Wind moves more water particles from the surface of other leaves

This means there is more space for water in the stomata to evaporate out

More wind means water evaporates faster so transportation happens more quickly
